Detailed Description

AI controller specifically made for the spider robot.

The spider robot (or mine-bot) which is got from the Unity Example Project can have this script attached to be able to pathfind around with animations working properly.
This script should be attached to a parent GameObject however since the original bot has Z+ as up. This component requires Z+ to be forward and Y+ to be up.

It overrides the AIPath class, see that class's documentation for more information on most variables.
Animation is handled by this component. The Animation component refered to in anim should have animations named "awake" and "forward". The forward animation will have it's speed modified by the velocity and scaled by animationSpeed to adjust it to look good. The awake animation will only be sampled at the end frame and will not play.
When the end of path is reached, if the endOfPathEffect is not null, it will be instantiated at the current position. However a check will be done so that it won't spawn effects too close to the previous spawn-point.

Note

This script assumes Y is up and that character movement is mostly on the XZ plane.

Member Function Documentation

override Vector3 GetFeetPosition ( )

virtual

Reimplemented from AIPath.

override void OnTargetReached ( )

virtual

Called when the end of path has been reached.

An effect (endOfPathEffect) is spawned when this function is called However, since paths are recalculated quite often, we only spawn the effect when the current position is some distance away from the previous spawn-point

Reimplemented from AIPath.

new void Start ( )

virtual

Starts searching for paths.

If you override this function you should in most cases call base.Start () at the start of it.

RepeatTrySearchPath

Reimplemented from AIPath.

new void Update ( )
